Kinetics/Equilibrium
Kinetics & Equilibrium Vocab
| Question | Answer |
|---|---|
| kinetics | the study of the factors that govern how rapidly reactions occur |
| collision theory | the rate of a reaction is proportional to the number of collisions that occur each second between the reactants |
| effective collision | a collision in which the colliding particles approach each other at the proper angle and with the proper amount of energy |
| catalyst | a substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process |
| inhibitor | one that inhibits, as a substance that retards or stops a chemical reaction |
| enzyme | any of numerous proteins or conjugated proteins produced by living organisms and functioning as biochemical catalysts |
| activation energy | the minimum kinetic energy that must be possessed by the reactants in order to give effective collision (one that produces products) |
| potential energy diagram | a plot of the change in potential energy that occurs during a chemical reaction |
| transition state | the moment during a reaction when the species involved have acquired the minimum amount of potential energy needed for a successful reaction |
| reaction rate | how quickly the reactants disappear and the products form |
| reversible reaction | a reaction in which the equilibrium constant is such that the reaction can be made to proceed at a detectable rate in either direction under appropriate conditions; results in an equilibrium mixture of reactants and products |
| Le Chatelier's principle | when a system that is in dynamic equilibrium is subjected to a disturbance that upsets the equilibrium, the system undergoes a change that counteracts the disturbance and, if possible, restores the equilibrium |
| stress | an applied force or system of forces that tends to shift a reaction |
| endothermic | characterized by or causing the absorption of heat |
| exothermic | releasing heat |
